calculus

 [kal´ku-lus] (pl. cal´culi) (L.)
an abnormal concretion, usually composed of mineral salts, occurring within the body, chiefly in hollow organs or their passages. Called also stone. See also kidney stone and gallstone. adj., adj cal´culous.
biliary calculus gallstone.
bladder calculus vesical calculus.
bronchial calculus broncholith.
calcium oxalate calculus oxalate calculus.
dental calculus a hard, stonelike concretion, varying in color from creamy yellow to black, that forms on the teeth or dental prostheses through calcification of dental plaque; it begins as a yellowish film formed of calcium phosphate and carbonate, food particles, and other organic matter that is deposited on the teeth by the saliva. It should be removed regularly by a dentist or dental hygienist; if neglected, it can cause bacteria to lodge between the gums and the teeth, causing gum infection, dental caries, loosening of the teeth, and other disorders. Called also tartar.
gastric calculus gastrolith.
intestinal calculus enterolith.
lung calculus a hard mass or concretion formed in the bronchi around a small center of inorganic material, or from calcified portions of lung tissue or adjacent lymph nodes. Called also pneumolith.
mammary calculus a concretion in one of the lactiferous ducts.
nasal calculus rhinolith.
oxalate calculus a hard urinary calculus of calcium oxalate; some are covered with minute sharp spines that may abrade the renal pelvic epithelium, and others are smooth. Called also calcium oxalate calculus.
phosphate calculus a urinary calculus composed of a phosphate along with calcium oxalate and ammonium urate; it may be hard, soft, or friable, and so large that it may fill the renal pelvis and calices.
prostatic calculus a concretion formed in the prostate, chiefly of calcium carbonate and phosphate. Called also prostatolith.
renal calculus kidney stone.
staghorn calculus a urinary calculus, usually a phosphate calculus, found in the renal pelvis and shaped like the antlers of a stag because it extends into multiple calices.
urate calculus uric acid calculus.
urethral calculus a urinary calculus in the urethra; symptoms vary according to the patient's sex and the site of lodgment.
uric acid calculus a hard, yellow or reddish-yellow urinary calculus formed from uric acid.
urinary calculus a calculus in any part of the urinary tract; it is vesical when lodged in the bladder and renal (see kidney stone) when in the renal pelvis. Common types named for their primary components are oxalate calculi, phosphate calculi, and uric acid calculi. Called also urolith.
uterine calculus any kind of concretion in the uterus, such as a calcified myoma. Called also hysterolith and uterolith.
vesical calculus a urinary calculus in the urinary bladder. Called also bladder calculus.

enterolith

a calculus in the intestine; they achieve their greatest importance in horses where they can cause obstruction of the large intestine. In most cases the resulting attacks of colic are recurrent. The enteroliths are smooth, lamellated objects consisting of ammonium magnesium phosphate and occur in mature animals.

Permanent colostomy which is required in some cases of this disease can result in some rare complications such as enteroliths formation, as illustrated in the case we are presenting here related to a 28-year-old male who reported at urology emergency with features of urinary and acute large bowel obstruction.
The more distal of the two enteroliths caused urinary retention and hence acute renal failure, and the proximal one caused large bowel obstruction by compressing the proximal loop of colostomy.
It was dilated and both enteroliths were crushed and removed partially to allow drainage of rectum backward through stoma.
One study classified enteroliths into two classes, primary which are formed within the lumen of bowel by concretions of normal chylous substances such as choleric acid, calcium phosphate and calcium carbonate.
Secondary enteroliths are caused by the migration of renal stones or gallstones.

On the other hand, there are fewer than 100 reported cases of primary enterolith causing SBO (6,7).
Enterolith intestinal obstruction owing to acquired and congenital diverticulosis; report of two cases and review of the literature.
CONCLUSION: In the clinical setting of a SBO due to a mass, enteroliths must be considered in the differential diagnosis when there is no evidence of gallstone ileus or malignancy.
